Abstract

The present invention has been made to execute speed change control appropriately under any traveling condition during an up-shift control in speed change by change-over, without increasing the number of control logic. Engagement side hydraulic pressure for the friction element to be engaged sweeps up as a result of arithmetic operation by torque phase speed change control. Disengagement side hydraulic pressure for the friction element to be disengaged is calculated by initial speed change control, dependent on the engagement side hydraulic pressure. The engagement side hydraulic pressure acts primarily and the disengagement side hydraulic pressure carries out follow-up control dependent on the engagement side pressure. Consequently, the same control can be executed regardless of power-on state or power-off state and regardless of a vehicle traveling condition. Accordingly, speed change control can be always executed on the same control stage.
